Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for sending an emergency message to each terminal in an online data processing system when the center system goes down.

Generally, in a system like the one shown in Figure 1, if a failure occurs in the center side system HOST and online operations become unavailable, the monitoring device SuP (supervisor)
displays a message to that effect and provides instructions to the operator. When the operator instructs the operator to disconnect the line, each communication control device CCP1 to CCPn rejects the communication request from the terminal and sends an emergency message (for example, ``There is a problem at the center. Please wait for a while.'') Send to all terminals. The SuP is equipped with a display DSP, keyboard KB, etc., and can perform system startup and configuration control, as well as various diagnostic functions and fault detection functions.

In the conventional emergency message sending method, as mentioned above, certain messages can be sent simultaneously from all CCPs based on instructions from the SuP.
In order to send a more detailed message, it was necessary to operate the operation panel of each CCP to create or select an appropriate message, which was extremely troublesome.

The present invention aims to eliminate these drawbacks and to enable appropriate messages to be sent to all CCPs at the same time by simple operations from the SUP.

FIG. 2 is a block diagram of an embodiment of the present invention.
Each CCP has an interface unit INT with the HOST, a line control unit LCU, a control unit CONT, and a memory MM.In addition to the CCP control program NCP, the MM has multiple messages EM0, EM2, EM3,
...remember.

In addition, on the SUP side, data SEL of the emergency message selection screen is stored in the external storage DK. The display device DSP is assumed to be capable of inputting data in a menu format using a screen display using a light pen or cursor operation.

In the event of a HOST failure, a message to that effect is first displayed on the display, as in the past, and when the operator instructs the line to be disconnected, each CCP operates in the same manner as described above. For example, the first message EM0 among multiple messages is automatically selected and all CCPs are
are sent all at once. Along with this, the message selection screen is read from the DK in SUP.
Displayed on DSP. The operator selects an appropriate message depending on the type and degree of failure. For example, in a message that says, "Please wait for a while as recovery is expected to take x minutes." x can contain several numbers. It is also possible to send a message stating that only a specific one of a plurality of online services is available. These various messages may be numbered in advance, and the operator may specify only the number.
The message text may also be displayed.

The operator's selection results will be notified to each CCP,
Based on the notification result, the CCP reads the corresponding one from among EM1, EM2, etc. stored in itself and sends it to each terminal connected to itself. It is best to provide an interface between SUP and CCP separately from the interface for normal data transfer (to ensure operation even in the event of a HOST failure).

In general, the emergency message may be the same for each CCP, but may be changed as necessary. For example, the same message may be sent in Japanese to a Japanese user, and in English to a foreign user.

As described above, according to the present invention, in addition to the fixed message as the first report, the second and subsequent messages selected according to the failure situation can be sent simultaneously from each CCP to each terminal by operation from the SUP. This allows for detailed responses to be made without any burden on the operator.

Claims (1)

[Scope of Claims] 1. Data comprising a large number of terminal devices connected to a center-side system via one or more communication control devices, and a monitoring device equipped with a display means to monitor and control the center-side system. In the processing system, each communication control device stores a plurality of emergency messages, and the monitoring device includes selection screen display means for displaying a selection screen for the plurality of emergency messages, and a selection screen display means for displaying a selection screen for selecting the plurality of emergency messages, and a selection screen display means for displaying a selection screen for selecting the plurality of emergency messages. notification means for notifying each of the communication control devices, and when a failure occurs in the center system, the display means displays the selection screen on the display of the monitoring device; When one is selected, the notification means notifies each communication control device of the selected result, and each communication control device selects the corresponding emergency message based on the notification and each terminal connected to the communication control device selects the corresponding emergency message. An emergency message sending method characterized in that the message is sent to a device.
